isJDK_N_OrHigher() method having issue with Java 10

[gaurav072]

I have found one of the issue with method isJDK_N_OrHigher() in EnvUtil class in audit4j-core 2.5.0

private static boolean isJDK_N_OrHigher(int n) {
        List<String> versionList = new ArrayList<String>();
        // this code should work at least until JDK 10 (assuming n parameter is
        // always 6 or more)
        for (int i = 0; i < 5; i++) {
            versionList.add("1." + (n + i));
        }

        String javaVersion = System.getProperty("java.version");
        if (javaVersion == null) {
            return false;
        }
        for (String v : versionList) {
            if (javaVersion.startsWith(v))
                return true;
        }
        return false;
    }

As the list containing 1.x and matching with system java version. It works fine upto Java 1.8 but from Java 10 versioning has been changed(10.x) due to which validation is failing. Could you please look into this.

Have you get any chance to look into this?

this does not work with jdk 9 :

Audit4j:INFO Initializing Audit4j... Audit4j:ERROR Your Java version (9.0.4) is not supported for Audit4j. see http://audit4j.org/errors#javaVersion for further details. Audit4j:ERROR Failed to initialize Audit4j: Java version is not supported.

Java 9 was not a stable release, Oracle already removed it from the website. https://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848520.html
